Important: This firmware uses a different file system that is not compatible with the file system of the stable version (1.18.0 at the time of this post) and there is no migration. All scripts on your device will be lost when switching between the stable and development firmware!

To flash the new firmware, please choose Type: development in the firmware update tool (make sure you're using the latest version as the firmware packages rely on the new script engine in the firmware updater!)
